Erm, prayer did not help, fact. That is what the study showed.
Are you saying that God helps those who pray, but not those who pray but are in part of a scientific experiment?
How annoying is that. Your family prays for you. God has a look "ahh, they're praying, let's use a bit of my ompipotence here... what the... scientists? experimenting if prayer works? I will not 'perform miracles to entertain on demand', I'm outta here!"
Sorry, just doesn't sound believable.
